About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1242085369. Listed at 20 retailers as of October 30, 2026, with prices from HK$4,921 to HK$21,538, a HK$16,616 spread on the same certified stone. NZ Jewellers lists it at HK$21,538. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
